• C.Only one version of STP can be active on a device at one time
• D.switches in each path
• E.MST supports up to four MST instances, including instance 0

Refer to the exhibit.

What are two effects of the given network configuration? (Choose two.)

• A.The 192.168.12.0/24 network is added to R3 database.

• C.R2 and R3 fail to form an adjacency.
• D.The 192.168.12.0/24 network is added to R3 route table.
• E.R1 and R2 fail to form an adjacency.
• F.R2 advertises the 192.168.23.0/24 network.

You are backing up a server with a 1 Gbps link and a latency of 2 ms.
Which two statements about the backup are true? (Choose two.)

• A.The default TCP receive window size is the limiting factor.
• B.The bandwidth delay product is 2 Mb.
• C.The bandwidth delay product is 50 Mb.
• D.The default TCP send window size is the limiting factor.
• E.The bandwidth delay product is 500 Mb.

Refer to the exhibit, while troubleshooting a connection failure on R1, you determine that F0/0 is down as shown, but the static route toward 172.168.0.0/16 still uses 192.168.12.2 as the next hop.

Which action can you take so that the floating static route through interface F0/1 is used when F0/0 is down?

• A.Configure the floating static route with an Administrative Distance of 255 instead of 250
• B.Configure the floating static route with an Administrative Distance of 100 instead of 250
• C.Configure the primary route with both the next hop IP address and the egress interface
• D.Configure the floating static route with the egress interface of the next hop IP address

Which flag in a configuration BPDU instructs all switches to shorten their bridge table aging process from the default 300 seconds to the current forward delay value?

• A.topology change acknowledgment bit
• B.topology change bit
• C.max-age bit
• D.priority bit
